"Lord of the Castle!"

Everyone exclaimed, but no one dared to step forward and shrank back.

The metal door was fully open.

Inside seemed to be a long hallway, very dark, with an unbearable chill and rancid stench wafting through it.

Pale light invaded part of the space inside the door, barely visible to the walls, the walls on either side of the hallway behind the door were dark red, uneven, and covered in some kind of disgusting pus.

The deadly tentacle reached out from the shadows deep in the hallway, wriggling and piercing through Yu Tuo's body.

"Bugs?"

Yu Tuo's tone was indifferent, and an alloy blade stretched out from his right arm.

He slashed at the ground, and the cold blade instantly severed the tentacles in front of him.

"Katsa—"

The fractured surface of the tentacle actually splattered out a dark brown bloody liquid, not like Terran blood, nor like Zerg blood.

The tentacles that remained on Yu Tuo's abdomen struggled and twisted like a skinned viper body.

Yu Tuo pulled the tentacle out of his steel body with a hard pull.

This thing seems to be still conscious, even if it is separated from the main body and firmly held in Yu Tuo's hand, the pieces of dark red metal scale armor at its tip are still wriggling regularly, stabbing at Yu Tuo from time to time, trying to cause damage to Yu Tuo.

"Humph!"

Yu Tuo snorted coldly and squeezed hard.

A huge burst of energy erupted from his hard steel palm, instantly turning the middle of the tentacle into a mass of meat sauce.

The tentacles that had broken into two pieces fell to the ground, but they were still twisting, and their vitality was terrifyingly strong.

At this moment, in the corridor inside the door, there was a sudden sound of footsteps.

"Dash...... Da ...... Da ......"

The sound is from far and near, not hurried or slow.

Yu Tuo stared coldly at the door, the alloy protection on his back slowly opened, revealing a honeycomb-shaped launch nest, and the firepower of the rest of his body was ready.

He's the master of the city, and there's nothing here that he doesn't know!

But suddenly, the footsteps stopped.

Immediately after, everyone heard the sound of "card".

The hallway inside the door slowly receded to the sides, and the ceiling began to move upwards, as if it was giving way to something massive.

In a few moments, the narrow corridor was wide.

"Kaka Ka ......"

It was as if there were countless biting gears turning.

The wall in front of it, with its small alloy door, began to rise in its entirety, like a huge gate.

When the floodgates were raised, all the researchers in the room gasped.

"Hiss......"

They saw a terrifying creature that they had never seen before!

It's like a monster in the movie "Alien", but it's countless times stronger than Alien.

The black-brown body was extremely large, the rough and hard surface was crawling with dark blue lines, and four thick and deadly tentacles fluttered behind it, and the limbs were extremely strong.

It had flattened horns on the sides of its skull, small eyes that glowed a breathtaking blue, sharp bone spurs on its cracked jaws, and sharp teeth exposed.

"What kind of monster is that?"

"Bugs?"

"No, the bug doesn't have this class at all, it looks much scarier than the bug!"

“……”

Most of the researchers here are familiar with the species and habits of bugs.

The terrifying creature in front of him, although not a bug, has some of the characteristics of a bug.

What's even more terrifying is that its bone spurs, claws, tentacles and other key parts have a large amount of dark red metal, which seems to grow directly from blood and bones.

It's a terrifying combination of flesh and machine, beyond the limits of most researchers' imagination.

The terrifying spiritual energy fluctuation on its body had also reached level 4, and it was not weaker than Yu Tuo standing outside the door!

"Hugh ——!"

It actually made a direct move, and a tentacle on its back instantly attacked Yu Tuo.

The pieces of metal scale armor at the tips of the tentacles shimmered with bloody light.

It was this thing that ran through Yu Tuo's body just now.

But Yu Tuo just snorted coldly this time, and his left hand and right hand kicked out the blade together, cutting off the tentacle that attacked him in the blink of an eye.

"Not bad!"

In the depths of the opposite passage, a compliment suddenly sounded.

I don't know if I'm praising Yu Tuo or praising this terrifying creature.

The footsteps rang out again.

"Dash...... Da ......"

Under everyone's gaze, a humanoid machine slowly stepped out of the shadows.

His facial features were very standard, wearing a black suit, holding a brown cane, and his movements were gentle, like a gentleman of the old times, and he slowly walked to the monster's side.

The monster was like a pet he had, and it had no hostility towards him, and it crouched gently beside him.

"Yes, I'm very happy with your performance." The robot wore white gloves and moved gracefully, slowly stroking the monster's low head.

He was really praising the monster, and he didn't pay attention to Yu Tuo outside at all.

Yu Tuo asked indifferently, "Who are you?" ”

"Me?"

The robot smiled and walked slowly forward with a cane.

He stepped out of the passage and into the testing area, as if to announce to everyone, "I am the lord of this city, and you can call me Mercer." ”

"Did Lord Eiffel ask you to come?"

"Well, your half-human, half-machine brain is pretty useful."

As Su Xia guessed, Yu Tuo used to be a human, and later, in order to pursue power, he transformed himself into a machine little by little, and finally completely surrendered to the mechanical clan and became what he is now.

In him, there are very few parts that can be called "human".

He's not alone, and there are some humans who have been modified.

During the war between the Cymblanx and the Zerg, there was a heated debate about who was the "Perfectly Evolved Race".

Later, the Machines began to demonstrate the feasibility of every evolutionary route, even some very evil evolutionary paths, and they were willing to try it.

Yu Tuo is one of the results of one of these routes.

And the creature in front of everyone, which has both zerg, mechanics, and even a little bit of human characteristics, is the result of another evolutionary path.

"How long has this experiment begun?" Yu Tuo asked indifferently.

"I was here before you ruled the city." Mercer smirked, "Your authority is not enough to know these things. ”

"The chaos of the Zerg is uncontrollable!"

Yu Tuo looked coldly at the creature in the passage, with awe-inspiring killing intent.

His perception is acute.

From that thing, he felt chaos, violence, madness, and other emotions, even more violent than many of the bugs held in the test area.

But this thing is smarter than a bug, knows how to endure, like a scheming human, and now submits to Mercer like a good dog.

Yu Tuo didn't believe that Mercer couldn't perceive it, so he asked, "Do you really think you can control it?" ”

"Watch the tone you speak to me!"

Mercer suddenly put away the smile on his face and slammed the ground with his cane.

But Yu Tuo's tone was still tough: "The Zerg gene can't be controlled, and you will eventually fail." ”

"Really?"

Mercer slowly lifted his cane, his eyes lit up with blue light.

……

At six o'clock in the morning, the whole city was still half-asleep.

The previous city-wide raid disturbed the dreams of countless people, and now the city residents are making up for sleep.

But suddenly, there was an earth-shattering noise in the mechanical clan base.

"Boom!"

It was as if countless explosives exploded, and the whole city trembled.

Suddenly, the lights were turned on in every house, and countless people woke up from their sleep.

"What's going on? Earthquake? ”

"No, it's like something exploded......"

“……”

People have already had the experience of letting their children hide in safe areas.

The closer you get to the mecha base, the stronger the tremor becomes, as if a monster is about to crawl out of the ground.

Not long after, there was another loud bang.

"Boom!"

The front of the building in the mechanical base shattered.

A mutilated body shattered the building's glass and was knocked upside down, slamming into the plaza outside the base building, knocking the plaza out of a deep pit.

The robots and humans working in the building were shocked.

Because the creature that was sent flying turned out to be their city lord Yu Tuo!

He's the master of the city, and who can beat him like that?

Moreover, the two sides actually fought from the ground, which means that the enemy is most likely an internal member.

At this moment, a black figure soared into the sky, high above, like a god looking at Yu Tuo below, and said indifferently: "The permission of the experimental area, what I give you is yours, I don't give it to you, you can't grab it!" ”

The battle just now was completely overwhelming.

Yu Tuo struggled to get up from the pit, his body in tatters, one arm useless, revealing blackened pipes, and blue psionic solutions flowed from the fractures from time to time.

Mercer descended slowly, his staff still intact.

"The city has not changed under your rule." He walked to the edge of the pit, "Even a small trash fish that can control metal can't solve it, what's the use of you?" ”

The "little miscellaneous fish" in his mouth naturally refers to Su Xia.

To be able to call a level 4 creature in such a contemptuous tone, his strength can be imagined.

"Do you understand the importance of Coral City?" Mercer flicked his cane, "If this continues, anyone can come and step on the head of my mech, and there will be more and more trash fish in this city!" ”

"What do you want to do?"

Although Yu Tuo was seriously injured, his tone was still indifferent.

Mercer replied, "Follow me these days and study hard, and I will get rid of that trash fish myself!" ”

"Then I'll see!"

……

At the moment, in the southwest area of the city, in the pharmacy.

Daddy stood by the window, silently looking in the direction of the mechanical base, his old eyes full of calm, not knowing what he was thinking.

And Su Xia had already returned to the pharmacy.

The Oasis camp is too far away to go tonight.

He locked Zhao Si in a hidden location and planned to take him to the Oasis camp tomorrow night.

Su Xia wanted to use Zhao Si's blood to comfort all the deceased members of the Old North Wind Organization.

The reward for the mission [Life and Death Rescue] has been distributed.

Su Xia lay quietly on the bed and clicked on the most precious reward.

"Awaken the Second Psionic Talent ......"
